Which is better, a folding kettle or a portable water cup?

Higher heating efficiency: the folding kettle adopts a large-area heating chassis, which can make full use of heat energy and improve heating efficiency. However, the heating area of portable drinking cups is relatively small, and it takes a long time to boil water.

Large capacity: The capacity of folding kettle is larger than that of portable kettle, and it can burn more water, so it is suitable for family, office or outdoor travel. The capacity of portable drinking cups is relatively small, and it may take several times to boil water to meet the demand.
